MACHINE FOR ROLLING HORSESHOE-BARS.

SPECIFICATION forming part of Letters Patent No. 368,621, dated August23, 1887.

' Application filed November 29, 1886. Serial No. 120,144. (No model.)

To all whom t may concern,.-

Be it known that I, JACOB RUSSELL, a citi- Zen of the United States, anda resident of Brooklyn, Kings county, New York, have in.- vented certainImprovements in Machines for Rolling and Greasing Horseshoe-Blanks, ofwhich the following is a speciiication.

My invention relates to rolls for rolling and creasing a blank forhorseshoes of peculiar form; and the invention consists in the peculiarconstruction and arrangement of the collars and creases of the rolls,whereby I produce the peculiar form of blank desired.

The object is to produce a horseshoe-blankor rather a bar containing twoor more of such blanks-which shall have a series of calks and creasesfor the nails, and shall also be broad est on the upper or plain face(next the horses foot) and taper evenly at its lateral sides or edges,as will be hereinafter more fully described. To roll such a bar requiresa peculiar construction and arrangement of the rolls, and in this myimprovements consist.

In rolling` a bar that is designed for ahorseshoe with calks and creasesfor the nails, attempts have been made to employ what are known ascollar and groove7 rol1s,and other attempts have been made, also, to userolls with the creaser arranged on the upper roll to produce blanks ofthis general character;

,but from my own knowledge, and for reasons that will be hereinafterexplained, these have not been successful.

The main novel features of my invention consist in arranging one of thecollars on the upper roll and one on the lower roll, and in arrangingthe creaser on the lower roll.

I will first describe the construction of my rolls with reference to theaccompanying drawings, and then point out the advantages I attive ratherthan actual, as the blanks will vary in cross-section and length.

The rolls are mounted in substantially the ordinary way, A Arepresenting, in general, the two rolls, B, the frame in which they arerotatively mounted, and O O the usual screws bearing on the boxes of theupper roll, A. On

the upper roll is the collar 1),'of which d is the flange portion, and dthe coned portion. On the lower roll is a collar, E, which overlaps theconed at x, and the creaser F, which is overlapped by the iiange d ofcollarl D at y. Set-screws a a (seen in Fig. l) screw through the frameR and bear against the flanged boxes of the rolls. These serve to keepthe flanges on the collars pressed up tightly against the respectiveparts at .fr and y. The cone d is eX- actly the same Width as thecreaser F and enables the joints at x and y to both be made tight.

The collars and oreaser may be mounted on the rolls in the usual manner,or in any good way, and the details of this construction need not bedescribed.

Referring to Fig. 4., it will be seen that the collar E has arecess inits face at c, to receive a reduced part, f, oi the creaser-ring F. Theconed face 1 of the cone d forms the upper or plain face ofthe blank.The perpendicular face 2 of the flange d forms one of the inclinedlateral faces or edges of the blank. An inclined face, 3, on the collarE forms the opposite inclined lateral face or edge of the blank, and theereaser F forms the lower narrower face of the blank, in which areformed the creases for the nails, and on which are formed the raisedcalks. The transverse section of creaser F in Fig. 4 is taken throughthe highest elevation on the creaser, which elevation forms theindentation to mark the position of the nail-hole. The rolls, as hereinshown, are designed to produce a blank, G, like that illustrated in Fig.5, wherein g is the web' or body of the blank; g g', the heel-calks, g2,the double toe-calk; g3, intermediate calks; g", the creases in the webfor the nails, and g5 the indenta tions in said creases where thenail-holes are to be punched.

Referring to Fig; 2, which shows a creaser having aperipheral lengthorscope sufficient to form two blanks, G, f f represent recesses for IOOproducing the heel-calks; f2, the recess for producing the toe-calk3f3,the recesses for producing the intermediate calks; f4, the elevationsfor producing the nail-creasesin the web; f5, the projections (onelevations f 4) for producing theindentations g5 in the blank, and ficutters for indicating the points where the blanks are to be separated.These latter produce transverse indentations or creases in the bar atthe severing-points. I have particularly described the blank that thecreaser as herein formed will produce; but my rolls are equally Welladapted for rolling or forming any horseshoeblank having calks andcreases. As before stated, the lateral faces or edges of the blank taperdown from the ilat upper face ofthe blank to the tips of the calks; andin rolling the blank the perpendicular face 2 of the flange d forms oneof these edges and the face 3 forms the other. To effect this taperproperly I construct the face 3 to extend down to a point a little belowthe lowest recess in the face of the creaser-ring F-that is to say,those recesses that produce the calks. This enables the face 3 toproduce a smooth unbroken incline or taper on that edge of the bar. Informing the creaser-ring to fit upto the inclined face 3 the elevationson same are undercut, as seen in Fig. 4. 1

In rolling horseshoe-blanks of this general character severaldifficulties have been encountered, and` these I will describe in orderthat my mode of obviating them may be the better understood.

First. Thel blank when in the rolls is very hot, and consequently sosoft as to bend very easily, and in the ordinary collar and groove rollsit is found impracticable to properly deliver it, the lateral frictionof the collars thereon causing the blank to stick and wrap itself aroundthe creaser or rolls. This difficulty I obviate by arranging one fiangeon each roll, the perpendicular flange d on the upper roll acting byfrictional contact with the blank to lift the latter from the creaser F.This flange, for the reason that its face moves in a plane perpendicularto the axis of the roll, adheres more firmly to the blank than theinclined face 3 on collar E, and thus exerts a lifting force on theblank as it emerges from the rolls, which is in excess of or issufficient to counterbalance the force tending to cause the blank toadhere to the creaser and wrap itself around the same. This is a veryimportant feature of the rolls, as it enables them to deliver the blankor bar of blanks perfectly and at all times.

Second. At the margin of the blank, between the-nail-crease and edge ofthe blank, the metal is drawn out quite thin. This is seen at g in Figs.4 and 5; and owing to the elongation of the bar in the rolls this thinweb is apt, if the metal is very hot, to draw down or fail to iill, andif themetal is cooler or "short? said web is apt to break or crackacross in the rolling. I nd this to be the case where the creaser is onthe upper roll, and

particularly where the collars are both on one roll. In my rolls thisdifficulty is entirely obviated, and I believe this is due, in the main,to the arrangement of the creaser on the lower roll, the bar being thuspressed down upon the creaser, instead of the creaser being forced downinto the bar.

Third. It is well known to those skilled in working metals in thismanner that a iin 7 is apt to be formed on the blank or bar at itscorner by the forcing of the hot metal into the crevice between therolls; also, that this iin will be formed by preference at the' lower orunder side of the bar, and at that point where the bar is most subjectedto pressure in drawing or elongating it. Therefore the `fin on thisblank would be formed at the joint between the rolls adjacent to thatedge of the blank in which the creases are formed. I obviate thisdifficulty by the arrangement of the creaser on thelower roll and thecreasing elevations f 4 andv f5 next to collar E, thus throwing thejoint(fr in Fig. 4) at which such iin would otherwise be formed on the upperside. Thereis much less tendency toward the formation of a n at theother lower joint, (y in Fig. 4.) By arranging one collar-ange on theupper roll and the other on the lower roll I am enabled to keep theseflanges pressed up closely to the respective parts of the other roll, soas to avoid an open joint and to take uplooseness caused by wear; and inorder to lessen the amount of metal in contact and cause the rolls tofit the more closely together in their lateral contact at x and i, Iprefer to slightly recess the faces of cone d and creaser F, as seen ate e in Fig.

4, so as to leave only a narrow raised portion l of the faces of same tocontact and bear on the respective collar-flanges.

It will be seen, then, that the characteristic features of my improvedrolls are, the arrangement of one collar and ilange on each-roll, theaxes of the rolls being parallel, and the flanges overlapping theadjacent parts on the other roll; the arrangement, in rolls of thiskind, of the creaser on the lower roll 5 the arrangement of theperpendicular flange on the upper roll, which latter forms the upperplain face of the blank, and the arrangement of the elevations f* f 5,which form the nailcreases, next the flange on the lower roll. There aresome novel features of construction as well as arrangement. The reasonsfor these arrangements of the several parts have already been given, andI consider them essential in a roll for producing this general form ofcreased horseshoeblank.

I am aware that collar and groove rolls and creasers variously arrangedand constructed have been before employed for rolling horseshoe-blanks,examples of which may be found in the patents of Justus and Young, No.211,024, and Claude, No. 219,621, and I do not claim these; but I amalso aware that many of these forms of rolls have not proved successfulin practice for the reasons I have given.

IOO

vI IO In the patent of Justus and Young the axes of the rolls are notparallel, the creasers are on the upper roll, and the flange on theupper roll does not pass the collar on the lower roll, but reststhereon. In all of these respects the rolls described in this patentdiffer materially from mine.

Having thus described my invention, I claim- 1. A pair of rolls forrolling horseshoeblanks, having the creaser on the lower roll, and onecollar-fiange on the upper roll and the other collar-ange on the lowerroll, as set forth.

2. A pair of rolls for rolling horseshoeblanks, having the creaser onthe lower roll, and one collar-flange on the upper roll and the othercollar-flange on the lower roll, the axes of the rolls being parallel,as set forth.

3. A pair of rolls for rolling horseshoeblanks, having the creaser onthe lower roll, and one collar-flange on the upper roll and the othercollar-ange on the lower roll, the axes of the rolls being parallel, andthe faces of the overlapping flanges being planes at right angles to thesaid axes of the rolls,`as set forth.

4. A pair of rolls for rolling horseshoeblanks, having the creaser andone collar on the lower roll, the elevations on the creaser forproducing the nail-crease being arranged next to said collar, and havingthe other collar-flange on the upper roll, as set forth.

`5. In a pair of rolls for rolling horseshoeblanks, the combination ofthe collar on the upper roll, provided with a ilange, d, with its facearranged perpendicular to the axis of the roll, and a cone, d', thecollar-flange E on the lower roll provided with an inclined face, 3, anda creaser, F, on the lower roll, provided with the necessary elevationsto form the nailcreases, arranged adjacent to said face 3, as set forth.

6. The combination, with the collar-flanges on the rolls, of the cone dand the creaser F, both provided with recesses e e', as and for thepurposes set forth.

7. The combination, with the collar E, provided with an inclined face,3, and a recess, e, to receive a reduced part, f, of the creaserring, ofthe said creaser-ring provided with recesses in its edge to forni thecalks, said face 3 extending down to a point as low as the bottom of thedeepest recess in the edge of said creaser, for the purpose set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
